configs: fix overlay order so system inittab takes precedence

The nftables rootfs overlay was listed after system/rootfs, causing
its simplified inittab (rc.local only, no rcS) to silently overwrite
the system container's inittab.  This prevented any init.d service
script from running at boot.

Reorder overlays so system/rootfs is applied last and wins.

Fixes: fd109c0 ("configs: rename -> simplify")
